Abstract: Process and reactor for the preparation of ammonia at elev-ated pressure and temperature in an ammonia reactor, wherein a process stream of ammonia synthesis gas is suc-cessively passed through at least three catalyst beds with intermediate cooling of partially reacted synthesis gas leaving the catalyst beds by heat exchange in heat exchang-ers arranged between each catalyst bed. The process stream is obtained by combining prior to introduction into a first catalyst bed, a first feed stream of synthesis gas having been preheated through indirect heat exchange during the intermediate cooling of the partially converted synthesis gas and a second feed stream of synthesis gas for adjust-ment of temperature of the process stream. The first feed stream is passed successively through the interbed heat ex-changers for cooling the partially converted synthesis gas and space velocity of the synthesis gas is adjusted to be substantially in the same range in all catalyst beds.

Title: Wayside wheel lubricator
Inventor: KUMAR SUDHIR
IPC: B61K3/00
Filed: 2001-05-21
Granted: 2010-04-13
Abstract: A wayside lubricator for railroad cars has a number of sensors (9, 10, 11) mounted adjacent the track which detect the approach and passage of rail cars. A lubricant supply and a pressurizing system are mounted adjacent the track and in fluid communication with a control valve and spray nozzle (12). The spray nozzle (12) is aimed to shoot lubricant into a target zone when the control valve is opened. The spray nozzle (12) is turned on for a defined duration of time so that the quantity of the lubricant is kept under control. Application of the lubricant to the wheels of the locomotive is avoided by detecting locomotive wheels and leaving the valve closed until they pass. This invention reduces the friction between the wheel tread and rail on curves for the trailing cars and thus reduces the friction and the force that is experienced by the wheel flanges on curves.

Granted: 2007-02-06
Abstract: A first Group III nitride compound semiconductor layer 31 is etched, to thereby form an island-like structure such as a dot-like, stripe-shaped, or grid-like structure, so as to provide a trench/post. Thus, a second Group III nitride compound layer 32 can be epitaxially grown, vertically and laterally, from a top surface of the post and a sidewall/sidewalls of the trench serving as a nucleus for epitaxial growth, to thereby bury the trench and also grow the layer in the vertical direction. In this case, propagation of threading dislocations contained in the first Group III nitride compound semiconductor layer 31 can be prevented in the upper portion of the second Group III nitride compound semiconductor 32 that is formed through lateral epitaxial growth. As a result, a region having less threading dislocations is formed at the buried trench.

Inventor: KROCHAK DARRYL D
IPC: F16C19/10
Filed: 2002-08-26
Granted: 2008-01-08
Abstract: The present invention provides an improved thrust bearing for extreme service applications through the use of a novel bearing cage assembly and improved surface design of the external face of the circular inside sidewall of the bearing cage assembly and race components. The novel bearing cage assembly allows for an increase in the quantity and size of the roller elements contained within the bearing cage, compared to others known in the art, which substantially increases the thrust bearings' load capacity. Moreover, the employment of a smooth curved surface on the external face of the circular inside sidewall of the bearing cage assembly and race components effectively eliminates any sharp edges and corners which could otherwise damage the rotating shaft. Thus, the combination of these two features substantially increases the load capacity, wear and durability of the thrust bearing components.

Abstract: The present invention relates to a method and system for the continuous preparation of gasoline, kerosene, and diesel oil from waste plastics. The method comprises the steps of: subjecting a melt of the waste plastics to a first catalytic reaction in which the waste plastic melt is in contact with a nickel or nickel alloy catalyst to be dehydrogenated while being decomposed; subjecting the dehydrogenated and decomposed waste plastic melt to a fluid catalytic cracking, as a second catalytic reaction to produce a gasoline-based fraction at a high fraction; fractionating the cracked material into a gasoline-based fraction, a kerosene fraction, and a diesel oil fraction; and reforming the gasoline-based fraction to produce a high octane number gasoline. The present invention can apply to a small scale facility, not to apply to a large scale facility. Also, the present invention allows gasoline to be prepared from the waste plastics in a high fraction and an efficient manner, thereby contributing to resource reclamation and environment protection.
